Detailed Description

The command group class, which executes a set of commands internally, while showing just one item inside the command history. Undoing a command group would undo all commands inside the group.

Constructor & Destructor Documentation

CommandGroup() [1/2]

MCore::CommandGroup::CommandGroup

(

)

Default constructor. You can set the name of the group with SetGroupName() manually.

CommandGroup() [2/2]

MCore::CommandGroup::CommandGroup	(	const AZStd::string &	groupName,
		size_t	numCommandsToReserve = 3
	)

The constructor.

Parameters

groupName	The name of the command group, which is the name that will appear inside the command history.
numCommandsToReserve	Pre-allocate memory for a given amount of commands. This can be used to prevent memory reallocations.

~CommandGroup()

MCore::CommandGroup::~CommandGroup

(

)

The destructor. Please note that this does NOT delete the actual Command objects after the group has been executed. They are deleted by the command manager automatically.

Member Function Documentation

AddCommandString() [1/2]

void MCore::CommandGroup::AddCommandString

(

const AZStd::string &

commandString

)

Add a command string to the group. This will be added to the back of the list of commands to be executed when executing this group.

Parameters

commandString

The full command string, like you would execute using CommandManager::ExecuteCommand(...).

AddCommandString() [2/2]

void MCore::CommandGroup::AddCommandString

(

const char *

commandString

)

Add a command string to the group. This will be added to the back of the list of commands to be executed when executing this group.

Parameters

commandString

The full command string, like you would execute using CommandManager::ExecuteCommand(...).

Clone()

CommandGroup* MCore::CommandGroup::Clone

(

)

const

Clone this command group.

Returns

The clone of this command group.

GetAddToHistoryAfterError()

bool MCore::CommandGroup::GetAddToHistoryAfterError

(

)

const

Check whether this command group will be added to the history, even when one of the internal commands fails to execute. The default is true.

Returns

Returns false when the group will not be added to the history when one of the internal commands fails to execute, otherwise true is returned.

GetCommand()

Command* MCore::CommandGroup::GetCommand

(

size_t

index

)

Get a given command. The return value can be nullptr in case the group hasn't yet been executed or when the execution of this command failed.

Parameters

index

The command number to get the pointer to. This must be in range of [0..GetNumCommands()-1].

Returns

A pointer to the command, which can be nullptr.

GetCommandString()

const char* MCore::CommandGroup::GetCommandString

(

size_t

index

)

const

Get the command execution string for a given command inside the group.

Parameters

index

The command number to get the string for. This must be in range of [0..GetNumCommands()-1].

Returns

The command string for the specified command.

GetCommandStringAsString()

const AZStd::string& MCore::CommandGroup::GetCommandStringAsString

(

size_t

index

)

const

Get the command execution string for a given command inside the group.

Parameters

index

The command number to get the string for. This must be in range of [0..GetNumCommands()-1].

Returns

The command string for the specified command.

GetContinueAfterError()

bool MCore::CommandGroup::GetContinueAfterError

(

)

const

Check if we want to continue when one of the internal commands fails. If not, it will stop executing further commands. The default is true.

Returns

Returns false when the internal command execution will stop at the first error, otherwise true is returned.

GetGroupName()

const char* MCore::CommandGroup::GetGroupName

(

)

const

Get the name of the group. This is the name that will appear inside the command history also.

Returns

The name of the group.

GetGroupNameString()

const AZStd::string& MCore::CommandGroup::GetGroupNameString

(

)

const

Get the group name in form of a string object. This is the name that will appear inside the command history also.

Returns

The name of the group.

GetNumCommands()

size_t MCore::CommandGroup::GetNumCommands

(

)

const

Get the number of commands inside this group. Using AddCommandString will increase the number returned by this method.

Returns

The number of commands inside this group.

GetParameters()

const CommandLine& MCore::CommandGroup::GetParameters

(

size_t

index

)

const

Get the parameter commandline object for the given command. This is only set after executing the command. Otherwise the parameter list will be empty.

Parameters

index

The command number ot get the parameter list for. This must be in range of [0..GetNumCommands()-1].

Returns

The CommandLine object which represents the parameter list used during execution of the command.

GetReturnFalseAfterError()

bool MCore::CommandGroup::GetReturnFalseAfterError

(

)

const

Check whether the group returns false after calling CommandManager::ExecuteCommandGroup(). The default value is false.

Returns

Returns true if the group return false in case an error occurred.

RemoveAllCommands()

void MCore::CommandGroup::RemoveAllCommands

(

bool

delFromMem = false

)

Remove all commands from the group.

Parameters

delFromMem

Set to true if you wish to delete the Command objects from memory as well. Normally you shouldn't do this as the command manager handles this.

ReserveCommands()

void MCore::CommandGroup::ReserveCommands

(

size_t

numToReserve

)

Reserve space for a given amount of commands, to prevent reallocs.

Parameters

[in]

numToReserve

The number of command strings to reserve memory for. This will prevent reallocs when adding new commands.

SetAddToHistoryAfterError()

void MCore::CommandGroup::SetAddToHistoryAfterError

(

bool

addAfterError

)

Set whether to add the group to the command history if one of the commands failed to execute or not. The default value is true.

Parameters

addAfterError

Set to true if you wish the group to be added to the command history, even if an error occurred.

SetCommand()

void MCore::CommandGroup::SetCommand	(	size_t	index,
		Command *	command
	)

Set the command pointer for a given command number. Normally you will not be using this function as this is automatically set by the command manager.

Parameters

index	The command number to set the command pointer for. This must be in range of [0..GetNumCommands()-1].
command	The command to use.

SetCommandString()

void MCore::CommandGroup::SetCommandString	(	size_t	index,
		const char *	commandString

index	The command number to change the command string for. This must be in range of [0..GetNumCommands()-1].
commandString	The command string to use. This is the string you would pass to CommandManager::ExecuteCommand(...).

SetContinueAfterError()

void MCore::CommandGroup::SetContinueAfterError

(

bool

continueAfter

)

Set if we want to continue when one of the internal commands fails. If not, it will stop executing further commands. The default value is true.

Parameters

continueAfter

Set to true to continue even after an error, or false to stop when one of the commands fails to execute.

SetGroupName() [1/2]

void MCore::CommandGroup::SetGroupName

Parameters

groupName

The name of the group.

SetGroupName() [2/2]

void MCore::CommandGroup::SetGroupName

groupName

)

Set the name of the group, which is the name as it will appear inside the command history.

groupName

The name of the group.

SetParameters()

void MCore::CommandGroup::SetParameters	(	size_t	index,
		const CommandLine &	params
	)

Set the parameter list for a given command. Normally you will not be using this function as this is automatically set by the command manager.

Parameters

index	The command number to change the parameter list for. This must be in range of [0..GetNumCommands()-1]. Please note that this isn't needed to be set normally. With normal usage you would only specify the command string and nothing more.
